Summary: Wireless Communication Systems Laboratory #1
Objective
The objective is to teach students a basic digital communication system through
Matlab simulation. The students will be familiar with the following items:
Waveform generation
Signal detection
Various plots to quantify the performance of basic digital communication
systems: Bit-error-rate versus signal-to-noise-ratio, power spectrum, power versus
time, constellation plot, polar plot, and eye diagram.
Performance evaluation of the system in noise.
o A system in AWGN channel with a simple QPSK modulation and
rectangular pulse shaping filter.
o Polar, constellation, eye diagram before sampling
o BER vs. SNR
o Mean, variance, histogram, pdf and cdf analysis through Matlab etc.
o Concept of independence and correlation.
o Basic Fourier transform and spectrum of a signal
Carrier shifting the signal to Intermediate frequency (also introducing carrier
frequency offset)
Introducing phase offset and observing the effect on the system
